Tojall whom "it may concern:

Be it known that I, GEORGE J. Sci-mp1s, a cit zen of the'United Statesof America, re-

siding at Sandusky, in the county of Erie and State of Ohio, haveinvented certain new and useful Improvements inMet-al-Re- .yinforced-Concrete Columns, Posts, and the l Like; and I hereby declarethe following to,

be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which. it pertains to make and use.the same.

,This nvention relates to metal-reinforced concrete columns, posts andthe like, and has met'al'reinforcement which will render the for one ofits objects the provision of a column or section stronger and morereliable thanthe metal reinforced sections heretofore made. I I Vfurther object'is the provision of a concrete columnhaving a metalreinforcement which is inherently strong and rigid and consistsof partswhich can be easily and securely united or fastened together.

With these objects in'view, this invention consists in certain noveldetails of construction and combinations and arrangements of '-'metalreinforcement arranged and construct-.

"Fig. 2 is a transverse "secti'onsubstantially along the line '22, Fig. 1, looking downwardly. Fig. 3 isa vertical section of a portion of the metal reinforcement, the sectionbeing taken sub- 'stantially along the line .3--3 of'F 1g. 2, looking inthe direction indicated by the arrow.

. Fig. 4: is a vertical section of a portion of the. metalreinforcement, the section being,

taken substantially along. the line 4.4, Fig. Fig. 5 is an elevation ingtogether certain parts of the metal re- The vertical metal -.reinforcedconcrete "column, shown in Figs. 1 and 2, may be of any shapebut as hereshown is rectangular in cross fsection, forming whatis known as a squarecolumn;

The metal reinforcement for the column is of courseeinbedded in theconcrete 10'and f includes, a group or pluralityof vertical orsubstantially parallel upright rods 11 which I have here shown four rodsarranged in rectangular formation opposite or diagonally inward from thedifferent corners re spectivelyof the column. i J

The vertical or longitudinally extending or parallel rods 11' are tiedor secured together so' as to provide a metal reinforcement ofconsiderable inherent strength and stiffness, and the means which Iemploy for this-purpose includes a'rod 12 which is arranged spirallyabout the group of upright and parallel rods and has its convolutionsrigidly secured to and held in engagement wi'tli'the outer sides of thesaid parallel rods. As here shown the spiral rod 1201' the convolutionsthereof include portions 12 which are inclined with respect to theaxisof the column and with respect to the vertical rods, as shown in Fig. 1,and are in planes parallel respectively to the sides of the column, asshown .in Fig. 2, and portions 1'2 arranged opposite the corners of thecolumn column, as shown in Fig. 4:, and inclined with respect to thesides of the column, as shown in Fig. 2, said portions 12 'being, inengagement with and crossing the'diflerent vertical or upright rods 11.i H

To secure the convolutionsof the spiral rod 12 to the parallel rods 11',Ifemploy sheet-metal clips, each of which is provided with 'a centralportion forming a loop 13 which is radially arranged relative to theinner side of or receives one ofthe vertical rods 11, and havingsubstantially paraloutwardly bQYOllClfl-IG spiral rod and are thencedoubled or-re'turned. inwardly, formthe clip beingsubstantially?parallel to the sides 14 and 15. formed by the two sideloops 16 and '17 or the parallel sides 14 and lo and .19 and 19 of theclip are provided withinwardly exof these vertical-rods may be employedbut lel sides-14: and 15 which extend radially and inclined with respectto'the axis of the center of the column and extends around the The outerportions of the clip which are tending open slots 20 which ,as shownclearly inl 'igs. 1 4 and 5, are inclined with respect to the axls ofthe column, and the two slots 1n the difierent side loops or outerportions respectively of the clip are arranged the one higher than theother and receive a section of one of the convolutions of the spiralrod, in this case receiving-one of the portions 12 of the rod. The slots20 extend inwardly a sufficient distance to permit the portion 12 of thespiral rod to bear inwardly againstthe outer side of the correspondingvertical rod 11.

To clamp or hold the convolutions of the spiral rod 12 against the rods11, clamping members or securing devices, such, for instance, as taperedor wedge-shaped members 21 are inserted between the spiral rod 12 andthe bases or central portions of'the 'side loops ,6 and 17 of each clipand are preferably driven into place so as to form a very rigidmetal-reinforcing structure.

The clips and wedges will be employed for clamping or securing eachconvolution of the spiral rod 12 to all the vertical rods 11 so that thespiral rod is secured to each vertical rod at a large number ofvertically spaced points. 1

I do not desire to be confined to the exact details shown but aim in myclaims to cover all modifications which do not involve a departure from.the' spirit and scope of my invention.
